Experience, by capability.

Led bi-weekly instructional lab sections for 50+ students and supported the full educational cycle, including surveying field/laboratory supervision, grading of technical work, and computational problem-solving instruction. Worked with tools and concepts including Autodesk Civil 3D, AutoCAD, field surveying, and technical lab supervision.

Performed roadway safety and spatial-data validation work using ESRI ArcGIS Pro and STN/WISLR roadway overlays. Audited 2,136 crash records and achieved 94.5% accuracy verification for a Wisconsin Department of Transportation-related safety analysis workflow. Contributed logic improvements for reporting and safety-analysis validation.

Used this period to strengthen transportation-engineering skills after Indian Railways and before graduate study. Focus areas included traffic operations, GIS, PTV Vissim, mobility simulation, online coursework, and career transition toward advanced transportation systems.

Drafted and checked AutoCAD drawings for railway infrastructure including girders, bearings, bridges, subways, and related civil works according to Indian Railways guidelines. Worked on estimates, project documentation, drawing reviews, submittals, and coordination for infrastructure projects. Built practical experience in large-scale public infrastructure systems.

Developed site plans in AutoCAD, prepared Measurement Books, cost estimates, and Running Account Bills, supervised construction site activities, and maintained construction-safety tracking systems. Built early field experience in project execution, documentation, and coordination.

Completed summer industrial training at the Tata Consultancy Services IT Park construction site in Rajarhat Special Economic Zone, Kolkata. Observed construction site operations, documentation, and engineering coordination on a large building/infrastructure project.
